Description

Technical Field

[0001] This utility model belongs to the technical field of highway maintenance, and in particular relates to a maintenance operation platform for highway high-pier bridges. Background Technology

[0002] The maintenance of high-pier bridges on highways is a highly specialized and challenging system engineering project, with the core objective of ensuring the long-term safety and durability of these critical traffic nodes. Due to their slender structure and unique location, high-pier bridges face a series of unique challenges, including poor accessibility, high operational risks, and sensitivity to environmental loads. This makes their maintenance work significantly different from that of ordinary bridges. The maintenance of high-pier bridges requires the use of work platforms to support workers at their work positions. However, the practical use of highway high-pier bridge maintenance work platforms still has the following drawbacks: In order to maintain the stability of the operation, the maintenance platform for highway high pier bridges needs to use a counterweight structure. However, the counterweight structure is heavy. After the work is completed, when the platform is moved, the moving structure supporting the platform needs to be moved or disassembled at the same time, which can easily cause instability and affect the transfer stability of the moving structure. Secondly, when the highway high-pier bridge maintenance operation platform is in operation, it is equipped with a gate that can be opened and closed. After the operator enters the operation platform from the ground, the platform is lifted and attached by external lifting equipment. The gate reserved on the platform may be accidentally opened by the staff, which may cause safety hazards. Utility Model Content

[0003] The purpose of this utility model is to provide a highway high-pier bridge maintenance operation platform. By setting up a traveling vehicle, a fixed frame, a support rod and a hanging basket body, it solves the problems of insufficient stability of the moving structure of the highway high-pier bridge maintenance operation platform and the safety hazards caused by the accidental opening of the gate reserved on the traveling platform.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a maintenance platform for highway high-pier bridges, comprising a traveling vehicle, a fixed frame, support rods, and a hanging basket body. Two traveling vehicles are symmetrically arranged, with a guardrail fixed to the top edge of each traveling vehicle. Each guardrail is symmetrically fixed with a support rod at its top. A fixed frame is fixed to one short side of the top of the two support rods of the same guardrail. The two fixed frames are arranged close to each other. A hanging basket body is arranged below the two traveling vehicles. The traveling vehicles, fixed frame, support rods, and hanging basket body together constitute the support and load-bearing system of the hanging basket operation platform. The two traveling vehicles are symmetrically arranged and move synchronously through a synchronous controller, thereby smoothly moving the hanging basket body. A guardrail is provided on the top of the traveling vehicle to restrict the movement of the counterweight on it. Two support rods are symmetrically installed on the guardrail of each traveling vehicle to support a fixed frame. The two fixed frames are arranged facing inwards and are located above the hanging basket body.

[0005] Furthermore, the top of the traveling vehicle is provided with a rectangular array of counterweight blocks. All of the counterweight blocks are located on the top of the traveling vehicle. Multiple counterweight blocks are arranged in a rectangular array on the top of the traveling vehicle to provide counterweight for the traveling vehicle during operation and to prevent tipping during the installation or use of the hanging basket.

[0006] Furthermore, a protective frame is provided at the top edge of the fixed frame, and a counterweight block two is arranged in a rectangular array at the top of the fixed frame inside the protective frame. The top perimeter of the fixed frame is provided with a protective frame, and multiple counterweight blocks two are arranged in a rectangular array inside, which are used to balance the main body of the hanging basket during operation. The protective frame plays a limiting role to prevent the counterweight block two from accidentally falling off, and can be pushed out from the bottom for disassembly after the work is completed.

[0007] Furthermore, a reversing rod is fixed to the top of the support rod. The reversing rod is located at the top of the support rod away from the fixed frame. A connecting guide wheel is fixed to the top of the reversing rod and the end of the support rod away from the fixed frame. The reversing rod is installed at the top of the support rod, and its position is away from the fixed frame. The top of the reversing rod and the end of the support rod away from the fixed frame are both equipped with connecting guide wheels to guide the direction of the wire rope and initially change the force transmission direction of the wire rope.

[0008] Furthermore, a steel wire rope is fixed to the top of the support rod between the reversing rod and the fixed frame. The steel wire rope passes through the periphery of the connecting guide wheel at the top of the reversing rod and through the periphery of the connecting guide wheel at the end of the support rod. A hanging ring is fixed to the bottom end of each steel wire rope. One end of the steel wire rope is fixed to the section at the top of the support rod located between the reversing rod and the fixed frame, then passes around the connecting guide wheel at the top of the reversing rod and the end of the support rod, and finally the other end is connected to the hanging ring. This arrangement can change the direction of the steel wire rope and enhance the support tension, so that the hanging ring can be reliably connected to the underside of the high pier bridge.

[0009] Furthermore, a second guardrail is fixed to the top edge of the main body of the hanging basket, and connecting hooks are fixed to the two short edges of the top of the main body of the hanging basket. The connecting hooks are set inside the second guardrail. The second guardrail is provided around the top of the main body of the hanging basket for safety protection. Connecting hooks are installed on the two short edges of the top, located inside the second guardrail. The connecting hooks are used to hook the hanging ring at the bottom of the wire rope, thereby realizing the connection between the main body of the hanging basket and the traveling vehicle system, forming a stable aerial work platform.

[0010] This utility model has the following beneficial effects: This invention solves the problem of insufficient stability in the transfer of mobile structures for highway high-pier bridge maintenance operation platforms by setting up a traveling vehicle and a fixed frame. First, the traveling vehicle is moved and set up on the viaduct. Then, after the two traveling vehicles are moved to the appropriate position, the wire rope is clamped onto the connecting guide wheel at the top of the reversing rod, and then onto the connecting guide wheel on the support rod. The hanging ring is placed under the high-pier bridge. After the main body of the hanging basket is attached, the second counterweight is placed on the top of the fixed frame. At the same time, the second counterweight in the protective frame provides counterweight for the main body of the hanging basket during operation. After the work is completed, the second counterweight is pushed from the bottom of the fixed frame to push it out from the protective frame at the top of the fixed frame and remove it from the fixed frame. This makes the traveling vehicle more stable and safer during transfer.

[0011] This invention solves the safety hazard caused by accidental opening of the reserved gate on the walking platform by setting up a support rod and a hanging basket body. When the walking vehicle is aligned, the workers are first lifted and transported to the hanging basket body by the ground lifting equipment. Then, the hanging basket body is lifted by the lifting equipment. After the hanging basket body is raised, until the four hanging rings are aligned with the four connecting hooks on the top of the hanging basket body, the operators on the platform attach the connecting hooks to the four hanging rings. Thus, once the hanging basket body is set up under the high pier bridge, work can begin. During work, the workers and high pier bridge maintenance equipment are lifted to the guardrail at the top of the hanging basket body by the ground lifting or hoisting equipment. The workers walk down the lifting equipment and the high pier bridge maintenance work can begin. There are no reserved gates on the walking platform, which makes it less likely to be opened accidentally, thus improving safety. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0016] Please see Figure 1-3 This utility model is a maintenance operation platform for highway high-pier bridges, including a traveling vehicle 1, a fixed frame 2, support rods 3, and a hanging basket body 4. Two traveling vehicles 1 are symmetrically arranged and are controlled by a synchronous controller to move synchronously, so that the hanging basket body 4 is moved smoothly. A guardrail 102 is fixed at the top edge of the traveling vehicle 1. The traveling vehicle 1 is limited by the counterweight block 101 on its top through the guardrail 102. A support rod 3 is symmetrically fixed at the top of each guardrail 102. The support rod 3 supports the fixed frame 2 on it. The fixed frame 2 is fixed together at one short side of the top of the two support rods 3 on the same guardrail 102. The fixed frame 2 is used to counterweight the hanging basket body 4 when working. The two fixed frames 2 are arranged close to each other. A hanging basket body 4 is arranged below the two traveling vehicles 1. The hanging basket body 4 provides walking support when working.

[0017] Specifically, the top of the traveling vehicle 1 is provided with a rectangular array of counterweight blocks 101. All counterweight blocks 101 are located on the top of the traveling vehicle 1. When the traveling vehicle 1 is working, the counterweight blocks 101 provide counterweight to prevent the traveling vehicle 1 from tipping over when installing the hanging basket.

[0018] Furthermore, a protective frame 202 is provided at the top edge of the fixed frame 2. The top of the fixed frame 2 inside the protective frame 202 is provided with a counterweight 201 in a rectangular array. The fixed frame 2 limits the counterweight 201 at its top through the protective frame 202 to prevent the counterweight 201 from falling off. After operation, the counterweight 201 is pushed out from the bottom of the protective frame 202.

[0019] The operation process of this embodiment is as follows: During operation, the traveling vehicle 1 is first moved and set on the viaduct. After the two traveling vehicles 1 are started and moved to the appropriate position, the wire rope 303 is then clamped onto the connecting guide wheel 302 at the top of the reversing rod 301, and then clamped onto the connecting guide wheel 302 on the support rod 3. The hanging ring 304 is placed under the high pier bridge. After the main body of the hanging basket 4 is attached, the second counterweight 201 is placed on the top of the fixed frame 2. At the same time, the second counterweight 201 in the protective frame 202 is used to counterweight the main body of the hanging basket 4 during operation. After the operation is completed, the second counterweight 201 is pushed from the bottom of the fixed frame 2 to push the second counterweight 201 out of the protective frame 202 at the top of the fixed frame 2 and removed from the fixed frame 2. Specific Implementation Example 2

[0020] Please refer to Figures 4 and 5. Based on the first specific embodiment, a reversing rod 301 is fixed to the top of the support rod 3. The reversing rod 301 is set at the top of the support rod 3 away from the fixed frame 2. A connecting guide wheel 302 is fixed to the top of the reversing rod 301 and the end of the support rod 3 away from the fixed frame 2. When the support rod 3 is working, the direction of the wire rope 303 is initially changed by the reversing rod 301 and the connecting guide wheel 302 thereon.

[0021] Specifically, a steel wire rope 303 is fixed to the top of the support rod 3 between the reversing rod 301 and the fixed frame 2. The steel wire rope 303 passes through the circumference of the connecting guide wheel 302 at the top of the reversing rod 301 and through the circumference of the connecting guide wheel 302 at the end of the support rod 3. A hanging ring 304 is fixed to the bottom of each steel wire rope 303. After the steel wire rope 303 changes direction and increases the support tension through the connecting guide wheel 302 on the reversing rod 301 and the support rod 3, the hanging ring 304 is connected and installed under the high pier bridge.

[0022] Furthermore, a guardrail 402 is fixed to the top edge of the main body 4 of the hanging basket, and a connecting hook 401 is fixed to the two short edges of the top of the main body 4 of the hanging basket. The connecting hook 401 is set inside the guardrail 402. The main body 4 of the hanging basket protects the workers on it through the guardrail 402. The connecting hook 401 is hooked into the hanging ring 304, so that the main body 4 of the hanging basket is supported on the working surface.

[0023] The operation process of this embodiment is as follows: When the traveling vehicle 1 is aligned with the position, the workers are first lifted and transported to the main body 4 of the hanging basket by the ground lifting equipment. Then, the main body of the hanging basket is lifted by the lifting equipment. After the main body of the hanging basket 4 rises, until the four hanging rings 304 are aligned with the four connecting hooks 401 on the top of the main body of the hanging basket 4, the operators on the platform will attach the connecting hooks 401 to the four hanging rings 304. Once the main body of the hanging basket 4 is properly attached and set up under the high pier bridge, the work can begin. During the work, the workers and the high pier bridge maintenance equipment are lifted to the guardrail 402 on the top of the main body of the hanging basket 4 by the ground lifting or lifting equipment. The workers can then get off the lifting equipment and the maintenance work of the high pier bridge can begin.
